Wii Sports is best-selling game of all time, according to VGChartz

We're automatically skeptical of any reports coming out of an organization who uses the letter "Z" to pluralize, but we find it difficult not to believe in a recent finding from VGChartz (sigh), who claim that Wii Sports has surpassed Super Mario Bros. as the best-selling video game of all time. After compiling last week's software sales, they've concluded that Wii Sports has barely crept past the 40.24 million mark that kept SMB on top of the pile for a bajillion years.

Of course, its worth noting that both games were bundled with their respective platforms (except in Japan and South Korea, whose Wiis were Sports-less), greatly boosting their sales. We wouldn't be surprised if the report proves to be accurate -- nor would we be shocked if Nintendo is currently looking for the highest, broadest rooftop from which they can proclaim their latest sales triumph.
